Sea Renderings is a water robot made by Geir Andersen in 2010 with the aim of measuring water depths in lakes and running on Arduino Duemilanove:

The purpose of this robot is to have it log water depths along a predefined set of waypoints. It stores its data on memory sticks or on SD cards. The estimated runtime is about 24 hours and with a top speed of 3km/h it will travel roughly 72km. With a log entry for every 10m this would give us over 700 depth measurements with full GPS reference.

Geir’s project page is hosted at Let’s Make Robots, a free and volunteer based initiative produced and maintained by members of the robot building community. You can have a look at the documentation and some of the illustrations showing the output of the measurements done at Lake Riskedalsvatnet in Norway.

Mike Buss used an Arduino Duemilanove, Parallax RFID reader, micro servo, and piezo electric speaker to make a personalized, lockable keepsake box for his girlfriend’s birthday:

The outside of the box is really simple: it just contains a button and an RGB LED. When she presses the button, the LED lights up green or red depending on if the box is locked. When she waves one of the three personalized RFID cards over the box, a little tune plays and the box unlocks.

As part of the project I also did some cool trick with a Pololu pushbutton power switch to make the battery last a lot longer. Since the Arduino is only powered for a few seconds when listening for RFID tags, the battery lasts a lot longer. When the box is finished locking or unlocking (or after a small time delay), it sends a signal to the power switch to turn off the power and conserve battery life. The box has been running on the same 9V battery I put in 4 years ago!

Alright ! After a haitus and some odd but trivial glitches I am finally happy to declare the birth of ANTROBOT Ver 1.0.0. Its a 2 legged creature with a single purpose - to explore and traverse its surroundings. Powered by a Lithium-Ion Rechargeable Battery it is a joy to see it scamper through the room. The way it frolics is delightful and reminds me of a swaying pendulum. It is by no stretch of imagination complete.

What does it do?

Can take simple Forward, backwards, stop commands.

My robot is a hacked RC car controled by an Arduino Duemilanove. It has no sensors, but I have left room on my chasis so I can add some more later when I feel more comfortable around Arduino. Most of the time on this project was spent dealing with Arduino code and the motor shield.
